 a plurality of adhesive-free portions provided on the surface of the base, each of the adhesive-free portions being adjacent to at least one of the adhesive portions, wherein each of the adhesive-free portions is made up of a non-adhesive material. 
 
     
     
       2. The stretch release adhesive according to  claim 1 , wherein a gap exists between any two of the plurality of adhesive portions. 
     
     
       3. The stretch release adhesive according to  claim 1 , wherein the adhesive portion exhibits a strip shape. 
     
     
       4. The stretch release adhesive according to  claim 1 , wherein the plurality of adhesive portions are all rectangular strips, and respective length-to-width ratios of the plurality of adhesive portions are different. 
     
     
       5. The stretch release adhesive according to  claim 3 , wherein the adhesive portion extends along a length direction of the base. 
     
     
       6. The stretch release adhesive according to  claim 1 , wherein the surface of the base comprises a first surface and a second surface opposite to each other, both of the first surface and the second surface having the adhesive portion. 
     
     
       7. The stretch release adhesive according to  claim 6 , wherein the first surface is one of a flat surface, a curved surface, and an uneven surface, and the second surface is one of a flat surface, a curved surface, and an uneven surface. 
     
     
       8. The stretch release adhesive according to  claim 6 , wherein the adhesive portions on the first surface and the adhesive portions on the second surface are symmetric with respect to the base. 
     
     
       9. A housing assembly for an electronic device, comprising:
 a housing having a mounting cavity; and 
 a stretch release adhesive comprising a base; a plurality of adhesive portions, the plurality of adhesive portions being spaced apart from one another, each of the adhesive portions being provided on a surface of the base; and a plurality of adhesive-free portions provided on the surface of the base, each of the adhesive-free portions being adjacent to at least one of the adhesive portions, wherein each of the adhesive-free portions is made up of a non-adhesive material and wherein at least a part of the stretch release adhesive is bonded with an inner wall surface of the housing. 
 
     
     
       10. The housing assembly for the electronic device according to  claim 9 , wherein the housing is a magnesium alloy piece. 
     
     
       11. The housing assembly for the electronic device according to  claim 9 , wherein the housing is an aluminum alloy piece. 
     
     
       12. The housing assembly for the electronic device according to  claim 9 , wherein the inner wall surface of the housing has a rough zone, and at least the part of the stretch release adhesive is bonded with the rough zone. 
     
     
       13. The housing assembly for the electronic device according to  claim 9 , wherein a rough zone exists on the stretch release adhesive. 
     
     
       14. An electronic device, comprising:
 a housing assembly comprising a housing having a mounting cavity and a stretch release adhesive, the stretch release adhesive comprising a base; a plurality of adhesive portions, the plurality of adhesive portions being spaced apart from one another, each of the adhesive portions being provided on a surface of the base; and a plurality of adhesive-free portions provided on the surface of the base, each of the adhesive-free portions being adjacent to at least one of the adhesive portions, wherein each of the adhesive-free portions is made up of a non-adhesive material and wherein at least a part of the stretch release adhesive is bonded with an inner wall surface of the housing, and 
 a battery located in the mounting cavity and bonded with the stretch release adhesive. 
 
     
     
       15. The electronic device according to  claim 14 , wherein the surface of the base comprises a first surface and a second surface opposite to each other, both of the first surface and the second surface having the adhesive portion, and the battery is bonded with the adhesive portions on the first surface. 
     
     
       16. The electronic device according to  claim 15 , wherein the inner wall surface of the housing is bonded with the adhesive portions on the second surface. 
     
     
       17. The electronic device according to  claim 14 , wherein the adhesive portion of the stretch release adhesive has an extension direction consistent with a disassembly direction of the battery. 
     
     
       18. The electronic device according to  claim 17 , wherein an arrangement density of the plurality of spaced adhesive portions is gradually increased in the disassembly direction of the battery. 
     
     
       19. The electronic device according to  claim 17 , wherein the adhesive portion has a gradually increased width in the disassembly direction of the battery.
